SAMUEL H. DOLBEAR, OF SAN FRANCISCO, CALIFORNIA.

STORAGE BIN, DEN, AND THE LIKE.

- To all who-writ may concern:

Be it known that I, SAMUEL H. Donnnan, a' citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Storage Bins, Done, and thelike, of which the following is a specification, reference being had therein to the accompanying draw- This invention relates broadly to storage bins, dens, and the like, and more specifically to means for effecting the discharge of the contents thereof.

The object of the invention is to provide simple and effective instruinentalities for accomplishing the emptying of a bin, or the 'like.

Another object is to provide the bottom of a bin with a tiltable portionso that when raised on its fulcrum, it will 'at the same time dispose the mass supported'thereon so that said mass will attain a certain momentum during its discharge, whereby the bin may be quickly and thoroughly emptied of: its contents.

Still another object is to provide a con. struction of such form that it is unnecessary to move the bin itself in order to effect a discharge therefrom of: its contents. For this reason, there is a considerable economy of space over the character of bins'now in use which include aninclined bottom.

The invention in general seeks to provide a bin-structure which is particularly adapted for use in storing ore and the like and which structure, from an operative standpoint, will in tactical use possess ahigh degree of efiiciency, durability and convenience and which, structurally considered, will be of great simplicity.

Involved in the invention are other objects and advantages which will be obvious from the annexed drawings and from the following description.

The invention resides broadly in the features of construction and in the correlative aggroupment of its parts, all as exemplified in the structure hereinafter set forth, and the scope of application of which will be indicated in the claim hereto appended.

In order that the invention may be comurehended readily. drawings illustrating some of the possible embodiments and utiizations of the same are hereto appended as v Specification of Letters Patent. Patented Sept 17, 1918.

Application filed July 3, 1915. Serial No. 37,978.

Figure l is a view in rearelevation of a storage bin constructed in accordance one embodiment of my invention;

with

Fig. 2 is a view in vertical transverse sec tion of the same on the line 2-2, Fig. 1;

Fig. 3'is a similar. view showing the parts in a different-position;

4 is a top plan view of a modification;

Fig. 5 is a view in vertical transverse section of this modified formfon the line 5--5, Fig. 4; I

Fig. 6 is a similar view thereoP'with the parts shown in a different position; and

Fig. 7 is a view in vertical transverse section of another modification.

Referring to these drawings, the reference-character 1 designates the bin or den, generally, comprising a top portion 2, front and rear portions, 3 and 4, respectively, and a. bottom portion 5. The bin may be of any required form, material and dimensions. In this instance, the bin is shown as rectangular in form andas built of metal.

The bottom-portion 5 is, preferably and as shown, hinged at 6; that is, adjacent the front portion 3. -The latter is provided with a discharge-opening 7 which is controlled by a slidable'gate or door 8. A

tom-portion and, in the embodiment illustrated by way of example in Figs. 1 to 3, such means include a motor comprising a pair of elevating ropes or cables 10 which are secured tolugs 11 at opposite ends of the bottom portion and pass upwardly through the top of the bin and over juxtaposed pulleys or sheaves 12 and 13. These ropes or cables may be connected to a means for tilting the bottom in relation to the side sections, and here diagramn'iatically indicated by the letter W.

As "a means for holding the mass of ore or other contents of the bin away from, the inner surface of the rear portion thereof, a mass-moving shield 14 is provided. This, at its lower end is pivotally connected to the vided, through the opening 7-, onto the chute 9 and to a suitable receptacle juxtaposed thereto. As thebottom raises, the members of the shield 14 are caused to be brought into angular relation and the member 15 tends to throw forward the portion of the mass resting against it.

The bottom may be repositioned to normal by gravity due to its own weight after the ropes 10 are slackened.

In Figs. 4 to 6, I have shown a modification of the structure. This includes a movable bottom 19 hinged at 20 and carrying at its free end a pivoted shieldmember 21. In this instance, also, a different form of de vice is utilized for moving the bottom. Preferably and as shown, this comprises a motor 22, or a pair of motors, each consisting of a cylinder 23 and a fluid-actuated piston 24 movably disposed therein.

In Fig. 7, I have shown another modification. This includes a tiltable bottom 25 actuated by a motor M, similarly as in the modification just described. In this instance, however a weight-actuated apron'26 is employed. This is secured to the free end of the bottom 25 and'passes over a sheave 27 and carries at its other end a weight 28 outside of the bin. As the bottom rises, the weight pulls the apron upwardly. The mass is, by this means, always held away from the rea r portion of the bin.

From the foregoing, it will be perceived that I have succeeded in devising a binstruoture having a mass-supporting member which is tiltable on its hinge by means of a motor and having, also, a i'nass-holding shield which is movable with the supporting-member and operating, always, to hold the mass away from the rear wall of the bin. The structure is well adapted to achieve the several objects and ends in view and it is-compact in form and easily manipulated.

As the invention is susceptible of a con siderable range of modification without (leparture from the spirit thereof, it is intended that all matter in the foregoing descriptionand shown in the accoi'npanying drawings shall be regarded as illustrative and not in a limiting sense.

What I claim is:

A stationary bin structure comprising side and end sections and a bottom section joined to form a receptacle for materials; one of said sections being provided with an exit for the materials; said bottom section being hingedly connected at one end, to a portion of the receptacle and normally lying in a horizontal plane; the other end of said bottom section being movable vertically to expel materials through the exit; and a sec tion hingedly connected to the bottom section and cooperating with one of the other sections to expel materials through the exit when the bottom is lifted.

In testimony whereof I affix my signature in presence of two witnesses.
